The transformation of our industry has major implications
Key industry trendsOverall trend toward mobilityIT rules now apply to telecomIP technology drives voice/data convergenceSoftware displaces hardwareOpen standards displace proprietary technologiesIncreasing demand forbroadbandBorders between carrier and enterprise domains disappear
Implications for network operatorsConsolidation of operationsIncreasing competition among CATV companies, ISPs, fixed and mobile network operatorsEroding prices for voice services (VoIP)Need for new competitive offerings,e.g. Home Entertainment
Implications for enterprisesTelcom investment must reduce costsSecurity is a major concernDemand for outsourcingCustomer requirements are becoming more industry-specificDemand for workforce mobility
